Description

TECHNICAL FIELD

[0001] The disclosure relates to the technical field of shower enclosures, and in particular to an anti-detachment pivot core, a pivot door structure and a door.Description of Related Art

[0002] According to the design of the existing pivot door in a shower enclosure, the door leaf rotates around the convex shafts relative to the door frame through the door pivot portion. The door leaf and the pivot profile in the door pivot portion are always connected and fixed through gluing, which makes the glass panel in a suspended state. Considering the weight of the door leaf itself, if the glue loses its original stickiness due to aging or environmental factors, it may not be able to continue to support the door leaf firmly, and the glass panel that was firmly connected will face the risk of detachment. Once the glass falls off due to the loss of stickiness of the glue, it will easily cause injuries to people.SUMMARY

[0003] In order to overcome the defects or problems in the BACKGROUND, an objective of the disclosure is to provide an anti-detachment pivot core, a pivot door structure and a door. The anti-detachment pivot core or the pivot door structure can fix the door leaf to the anti-detachment pivot core or the door pivot portion when glue loses its stickiness, which prevents the door leaf from detachming and ensures safety of users.

[0004] In order to achieve the above objective, embodiments of the disclosure adopt, but not limited to, the following technical solutions:

[0005] A first technical solution relates to an anti-detachment pivot core for preventing a door leaf from detachment from a pivot profile along a second direction. The pivot profile extends along a first direction, and the door leaf is in an insertion fit with the pivot profile along the second direction. The door leaf is provided with a groove opening along the first direction. The anti-detachment pivot core is provided with a main body and an extending portion fixed to each other, and the main body is suitable to be in an insertion fit with a top end of the pivot profile along the first direction. The extending portion is provided with an anti-detachment protrusion and two clamping portions. The anti-detachment protrusion is suitable to be in an insertion fit with the groove to prevent the door leaf from detaching from the pivot profile along the second direction, and the two clamping portions are suitable to clamp the door leaf along a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0006] A second technical solution relates to a pivot door structure for rotatably connecting a door leaf to a door frame. The door frame is provided with first shaft connecting portions opposite to each other along a first direction. The door leaf is provided with a groove opening along the first direction. The pivot door structure is provided with a door pivot portion and an extending portion, and two ends of the door pivot portion are provided with second shaft connecting portions in rotatable fits with the two first shaft connecting portions along the first direction. The door leaf is embedded into the door pivot portion along a second direction. The extending portion extends out from one end of the door pivot portion along the second direction and is provided with an anti-detachment protrusion and two clamping portions. The anti-detachment protrusion is in an insertion fit with the groove, and the two clamping portions clamp the door leaf along a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0007] In a third technical solution based on the second technical solution, the pivot door structure includes the pivot profile, a first pivot core and the above anti-detachment pivot core. The first pivot core and the main body of the anti-detachment pivot core are respectively inserted into two ends of the pivot profile to form the door pivot portion together.

[0008] In a fourth technical solution based on the third technical solution, the first shaft connecting portions are convex shafts; and the second shaft connecting portions are shaft holes.

[0009] In a fifth technical solution based on the fourth technical solution, the pivot profile, the first pivot core and the anti-detachment pivot core are respectively provided with the shaft holes.

[0010] In a sixth technical solution based on the third technical solution, the anti-detachment pivot core is inserted into a top end of the pivot profile along the first direction.

[0011] In a seventh technical solution based on the third technical solution, the anti-detachment pivot core and the first pivot core are respectively provided with limit slots extending along the first direction and opening toward the second direction, and the door leaf is in an insertion fit with the limit slots along the second direction.

[0012] In an eighth technical solution based on any of the second to seventh technical solutions, a door includes the door frame and the door leaf respectively extending along the first direction. The door leaf and the door frame are rotatably connected through the above pivot door structure.

[0013] In a ninth technical solution based on the eighth technical solution, the pivot profile is in an interference fit with the first pivot core and the anti-detachment pivot core.

[0014] In a tenth technical solution based on the eighth technical solution, the pivot profile is provided with a mounting slot extending along a first direction and opening toward a second direction, and the door leaf is made of glass and fixed into the mounting slot through a glass glue layer.

[0015] As can be seen from the above description of the embodiments of the disclosure, compared with the prior art, the embodiments of the disclosure have the following beneficial effects:

[0016] In the first technical solution and related embodiments, the anti-detachment pivot core is provided with the anti-detachment protrusion which is in an insertion fit with the groove opening along the first direction in the door leaf, so that a firm anti-detachment mechanism is formed, which prevents the door leaf from detaching from the pivot profile along the second direction under the action of external force, and improves the safety and reliability of the pivot door structure. In addition to the anti-detachment protrusion, the extending portion of the anti-detachment pivot core is further provided with the two clamping portions, and the two clamping portions can clamp the door leaf along the third direction (perpendicular to both the first direction and the second direction), which prevents the door leaf from shaking in the third direction, avoids possible deviation or detachment of the door leaf during rotation and ensures the steadiness and safety of the door leaf during movement. In the anti-detachment pivot core, the main body and the extending portion are integrally formed, which ensures the rigidity of the extending portion. The main body is in an insertion fit with the top end of the pivot profile along the first direction, which makes the mounting easy and quick. Moreover, the anti-detachment protrusion and the clamping portions of the extending portion can be easily butted with the groove and corresponding positions on the door leaf, which reduces the mounting difficulty and cost.

[0017] In the second technical solution and related embodiments, the extending portion of the pivot door structure is arranged outside the door pivot portion, and the anti-detachment protrusion and the clamping portions are integrated into the extending portion, which realizes multiple anti-detachment protections for the door leaf and improves the safety and reliability of the pivot door structure. Specifically, the anti-detachment protrusion is in an insertion fit with the groove opening along the first direction in the door leaf, which prevents the door leaf from detaching along the second direction (i.e., perpendicular to the direction along which the door leaf is embedded into the door pivot portion). Moreover, the clamping portions clamp and limit the door leaf along the third direction (i.e., the direction perpendicular to both the first direction and the second direction), which prevents the door leaf from shaking in the third direction, avoids possible deviation or detachment of the door leaf during rotation and ensures the steadiness and safety of the door leaf during movement. In this structural design, the groove in the door leaf does not need to be too big, which ensures the beautiful appearance of the door leaf. During mounting, it is only required to embed the door leaf into the door pivot portion along the second direction and ensure the anti-detachment protrusion to be properly butted with the groove. This can reduce the mounting difficulty and improve the mounting efficiency.

[0018] In the third technical solution and related embodiments, the main body of the anti-detachment pivot core is inserted into the pivot profile, and the extending portion is deposed outside the pivot profile, which maintains the structural integrity of the main body of the anti-detachment pivot core, avoids the interference or influence of the extending portion on the structure of the main body, and avoids affecting the strength and stability of the main body of the anti-detachment pivot core. This structure also reduces the production difficulty of the anti-detachment pivot core.

[0019] In the fourth technical solution and related embodiments, the combination of the convex shafts and the shaft holes optimizes the space utilization of the pivot door structure. Since the convex shafts and the shaft holes are designed compactly, they can be effectively connected without occupying too much space. Moreover, the components in the pivot door structure can be connected to the door frame simply and quickly.

[0020] In the fifth technical solution and related embodiments, the pivot profile, the first pivot core and the anti-detachment pivot core realize opening and closing of the door leaf through the rotatable fits between the shaft holes and the convex shafts of the door frame.

[0021] In the sixth technical solution and related embodiments, the anti-detachment pivot core is inserted into the top end of the pivot profile along the first direction, which effectively prevents detachment of the top area of the door leaf. This design not only ensures the firmness of the door leaf, but also considers the cost and the simplicity of manufacture. During opening and closing of the door leaf, the top area of the door leaf is more susceptible to the external force, so the extending portion of the anti-detachment pivot core can specifically enhance the anti-detachment effect of this top area.

[0022] In the seventh technical solution and related embodiments, the first pivot core and the anti-detachment pivot core are respectively inserted to the two ends of the pivot profile, and the two ends of the door leaf are respectively in an insertion fit with the limit slots at the upper and lower ends along the second direction, which further prevents the door leaf from shaking in the third direction, avoids possible deviation or detachment of the door leaf during rotation and ensures the steadiness and safety of the door leaf during movement.

[0023] In the eighth technical solution and related embodiments, the door is mounted by adopting the pivot door structure, which ensures the stability and safety of the door during use.

[0024] In the ninth technical solution and related embodiments, the interference fit can ensure the pivot profile to be closely fitted with the first pivot core and the anti-detachment pivot core, thereby preventing looseness and detachment.

[0025] In the tenth technical solution and related embodiments, the door leaf is fixed in the mounting slot through the glass glue layer, which improves the strength of connection between the door leaf and the pivot profile.BRIEF DESCRIPTION OF THE DRAWINGS

The pivot profile 5 extends along a first direction, and the door leaf 2 is in an insertion fit with the pivot profile 5 along the second direction. As shown in FIG. 4, the door leaf 2 is provided with a groove 17 opening along the first direction. The anti-detachment pivot core 4 is provided with a main body and an extending portion 3 fixed to each other, and the main body is suitable to be in an insertion fit with a top end of the pivot profile 5 along the first direction. The extending portion 3 is provided with an anti-detachment protrusion 12 and two clamping portions 13. The anti-detachment protrusion 12 is suitable to be in an insertion fit with the groove 17 to prevent the door leaf 2 from detaching from the pivot profile 5 along the second direction, and the two clamping portions 13 are suitable to clamp and form an interference fit with the door leaf 2 along a third direction.

[0034] In this embodiment, the anti-detachment pivot core 4 is provided with the anti-detachment protrusion 12 which is in an insertion fit with the groove 17 opening along the first direction in the door leaf 2, so that a firm structure is formed, which prevents the door leaf 2 from detaching from the pivot profile 5 along the second direction under the action of external force, and improves the safety and reliability of the pivot door structure. In addition to the anti-detachment protrusion 12, the extending portion 3 of the anti-detachment pivot core 4 is further provided with the two clamping portions 13, and the two clamping portions 13 can clamp the door leaf 2 along the third direction (which is perpendicular to both the first direction and the second direction), which prevents the door leaf 2 from shaking in the third direction, avoids possible deviation or detachment of the door leaf 2 during rotation and ensures the steadiness and safety of the door leaf 2 during movement. In the anti-detachment pivot core 4, the main body and the extending portion 3 are connected into a whole, which ensures the strength of the extending portion 3. The main body is in an insertion fit with the top end of the pivot profile 5 along the first direction, which makes the mounting easy and quick. Moreover, the anti-detachment protrusion 12 and the clamping portions 13 of the extending portion 3 can be easily butted with the groove 17 and corresponding positions on the door leaf 2, which reduces the mounting difficulty and cost. The two clamping portions 13 is in an interference fit with the door leaf 2, which further improves the anti-detachment effect. The first direction (x), the second direction (y) and the third direction (z) are perpendicular to each other.Embodiment II

[0035] Referring to FIG. 1 to FIG. 10, as shown in FIG. 1 and FIG. 11, a pivot door structure for rotatably connecting a door leaf 2 to a door frame 7 is provided. The door frame 7 is provided with first shaft connecting portions opposite to each other along a first direction. Specifically, two ends of the door frame 7 are provided with the first shaft connecting portions opposite to each other. In this embodiment, the first shaft connecting portions are designed as convex shafts 18, which are used for forming rotatable fits with the second shaft connecting portions of the door pivot portion 1. As shown in FIG. 4, the door leaf 2 is provided with a groove 17 opening along the first direction. Specifically, the door leaf 2 needs to be matched with the door frame 7 in size and shape at the joint with the door frame 7, which ensures smooth rotation. The pivot door structure includes a door pivot portion 1 and an extending portion 3.

[0036] Two ends of the door pivot portion 1 are provided with second shaft connecting portions in rotatable fits with the two first shaft connecting portions along the first direction. The door leaf 2 is embedded into the door pivot portion 1 along a second direction. Specifically, the second shaft connecting portions are shaft holes. The combination of the convex shafts 18 and the shaft holes optimizes the space utilization of the pivot door structure.

[0037] As shown in FIG. 2 and FIG. 3, the extending portion 3 extends out from one end of the door pivot portion 1 along the second direction and is provided with an anti-detachment protrusion 12 and two clamping portions 13. The anti-detachment protrusion 12 is in an insertion fit with the groove 17.

[0038] For the clamping portions 13, as shown in FIG. 5, the two clamping portions 13 clamp the door leaf 2 along a third direction. Specifically, the two clamping portions 13 clamp the anti-detachment protrusion 12 along the third direction and form an insertion fit with the door leaf 2 along the second direction.

[0039] In this embodiment, the extending portion 3 of the pivot door structure is arranged outside the door pivot portion 1, and the anti-detachment protrusion 12 and the clamping portions 13 are integrated into the extending portion 3, which realizes multiple anti-detachment protections for the door leaf 2 and improves the safety and reliability of the pivot door structure. Specifically, the anti-detachment protrusion 12 is in an insertion fit with the groove 17 opening along the first direction in the door leaf 2, which prevents the door leaf 2 from detaching along the second direction (i.e., perpendicular to the direction along which the door leaf 2 is embedded into the door pivot portion 1). Moreover, the clamping portions 13 clamp and limit the door leaf 2 along the third direction (i.e., the direction perpendicular to both the first direction and the second direction), which prevents the door leaf 2 from shaking in the third direction, avoids possible deviation or detachment of the door leaf 2 during rotation and ensures the steadiness and safety of the door leaf 2 during movement. In this structural design, the groove 17 in the door leaf 2 does not need to be too big, which ensures the beautiful appearance of the door leaf 2 and also prevents dust from entering the groove 17. During mounting, it is only required to embed the door leaf 2 into the door pivot portion 1 along the second direction and ensure the anti-detachment protrusion 12 to be properly butted with the groove 17. This can reduce the difficulty of mounting and improve the mounting efficiency.

[0040] Specifically, the pivot door structure includes a pivot profile 5, a first pivot core 6 and an anti-detachment pivot core 4.

[0041] As shown in FIG. 5, the anti-detachment pivot core 4 is provided with a main body and the above extending portion 3. The first pivot core 6 and the main body of the anti-detachment pivot core 4 are respectively inserted into two ends of the pivot profile 5 to form the door pivot portion 1 together. In the anti-detachment pivot core 4, the main body and the extending portion 3 are integrally formed, which ensures the strength of the extending portion 3.

[0042] As shown in FIG. 7, the pivot profile 5 is a profile extending along the first direction. As shown in FIG. 8, the first pivot core 6 and the anti-detachment pivot core 4 are suitable to be inserted into the pivot profile 5. The pivot profile 5 is provided with a third shaft hole 20 in a rotatable fit with the convex shaft 18and an opening located at the third shaft hole 20 along the second direction, which forms a mounting slot 11 for the door leaf 2 to enter.

[0043] As shown in FIG. 6, the first pivot core 6 is provided with a first limit slot 14, the first limit slot 14 is suitable for insertion of the pivot profile 5 along a circumferential annular wall and provided with an opening in the annular wall along the second direction for the door leaf 2 to enter. A middle of the main body of the first pivot core 6 is provided with a first shaft hole 15 in a rotatable fit with the convex shaft 18.

[0044] As shown in FIG. 5, the anti-detachment pivot core 4 is provided with a second limit slot 21, the second limit slot 21 is suitable for insertion of the pivot profile 5 along a circumferential annular wall and provided with an opening in the annular wall along the second direction for the door leaf 2 to enter, and the extending portion 3 is located outside the second limit slot 21 along the second direction. A middle of the main body of the anti-detachment pivot core 4 is provided with a second shaft hole 16 in a rotatable fit with the convex shaft 18.

[0045] The anti-detachment pivot core 4 and the first pivot core 6 are respectively provided with the limit slots extending along the first direction and opening toward the second direction, and the door leaf 2 is in an insertion fit with the limit slots along the second direction. The first pivot core 6 and the anti-detachment pivot core 4 are respectively inserted into the two ends of the pivot profile 5, and the two ends of the door leaf 2 are respectively in an insertion fit with the limit slots at the upper and lower ends along the second direction, which further prevents the door leaf 2 from shaking in the third direction, avoids possible deviation or detachment of the door leaf 2 during rotation and ensures the steadiness and safety of the door leaf 2 during movement.

[0046] The pivot profile 5, the first pivot core 6 and the anti-detachment pivot core 4 realize opening and closing of the door leaf 2 through the rotatable fits between the shaft holes and the convex shafts 18 of the door frame 7. Specifically, the anti-detachment pivot core 4 is inserted into a top end of the pivot profile 5 along the first direction, and the first pivot core 6 is inserted into a bottom end of the pivot profile 5 along the first direction. The anti-detachment pivot core 4 is inserted into the top end of the pivot profile 5 along the first direction, which effectively prevents detachment of the top area of the door leaf 2. Even if glue loses its stickiness, the door leaf 2 can be prevented from falling off the pivot profile 5, thereby effectively protecting the personal safety of users. This design not only ensures the firmness of the door leaf 2, but also considers the cost and the simplicity of manufacture. During opening and closing of the door leaf 2, its top is more susceptible to the external force, so the extending portion 3 of the anti-detachment pivot core 4 can specifically enhance the anti-detachment effect of such top area. A bottom end of the pivot profile 5 along the first direction is close to the ground, and the bottom of the door leaf 2 is less susceptible to the external force during opening and closing of the door leaf 2, so the first pivot core 6 may not need the extending portion 3.Embodiment III

[0047] A door, as shown in FIG. 10, includes a door frame 7 and a door leaf 2 respectively extending along a first direction. The door leaf 2 and the door frame 7 are rotatably connected through the above pivot door structure. The door leaf 2 can rotate around the door pivot portion 1 smoothly, and an anti-detachment protrusion 12 and clamping portions 13 of an anti-detachment pivot core 4 can effectively prevent the door leaf 2 from detaching. When the door is mounted by adopting this pivot door structure, the stability and safety of the door can be ensured during use.

[0048] As shown in FIG. 11 and FIG. 12, the door includes a pivot seat 10, and the pivot seat 10 is provided with first shaft connecting portions opposite to each other along the first direction. Specifically, there are two pivot seats 10 that are mounted at the top end and the bottom end of the door frame 7 along the first direction, and the first shaft connecting portions are convex shafts 18. The convex shafts 18 are in rotatable fits with a first shaft hole 15 of a first pivot core 6, a second shaft hole 16 of an anti-detachment pivot core 4 and a third shaft hole 20 of a pivot profile 5. As shown in FIG. 11, the pivot seats 10 are fixed to the door frame 7 through screws 19.

[0049] The pivot profile 5 is in an interference fit with the first pivot core 6 and the anti-detachment pivot core 4. As shown in FIG. 3 and FIG. 9, the interference fit can ensure the pivot profile 5 to be closely fitted with the first pivot core 6 and the anti-detachment pivot core 4, thereby preventing looseness and detachment.

[0050] The pivot profile 5 is provided with a mounting slot 11 extending along a first direction and opening toward a second direction, and in this embodiment, the door leaf 2 is made of glass and fixed into the mounting slot 11 through a glass glue layer. Specifically, the mounting slot 11 is a gluing groove, and the door leaf 2 is fixed in the mounting slot 11 through the glass glue layer, which improves the strength of connection between the door leaf 2 and the pivot profile.

[0051] The specific assembly process is as follows: Firstly, the first pivot core 6 is inserted into one end of the pivot profile 5 in an interference fit manner while ensuring the first shaft hole 15 is aligned with the convex shaft 18 at one end of the door frame 7. Then, glass glue is applied into the mounting slot 11 of the pivot profile 5, and the door leaf 2 is mounted into the pivot profile 5 along the second direction.

[0052] Secondly, the main body of the anti-detachment pivot core 4 is partially inserted into the other end of the pivot profile 5 in an interference fit manner while ensuring the anti-detachment pivot core to correspond to the convex shaft 18 at the other end of the door frame 7 in position. In this case, the pivot profile 5, the first pivot core 6 and the anti-detachment pivot core 4 form the door pivot portion 1 together.

[0053] Finally, the anti-detachment protrusion 12 of the anti-detachment pivot core 4 is aligned with and inserted into the groove 17 of the door leaf 2 properly, and the two clamping portions 13 are made to clamp the door leaf 2 along the third direction.

[0054] The above description of the specification and embodiments are used to explain the scope of the disclosure, but does not constitute a limitation to the scope of the disclosure. Under the inspiration of the disclosure or the above embodiments, any modifications, equivalent substitutions or other improvements of the embodiments of the disclosure or a part of the technical features that can be obtained by those of ordinary skill in the art through logical analysis, reasoning or limited experiments in combination with common sense, ordinary skill in the art and / or the prior art shall fall within the scope of the disclosure.
